Sign for yourself

Sign life's big moments the way you unlock your phone.

Three moves you already know: the unlock gesture, a tap at each point the document requires your eyes, and a location stamp at the end. Sealed into a record anyone who holds it can check — new house, new card, new chapter.

The adventure

The waiver before the jump, signed at the airfield — and the record carries the where.

The signing, up close

Three taps you'll actually read.

A required point — tapped, not scrolled past.
The last tap seals it — You signed. Here.

The story of one signature

A signature used to be a line of ink.

✓ WHO — presence check ✓ WHEN — hash-chained ✓ WHERE — corroborated

Now it carries its witnesses — sealed, checkable by anyone who holds it.

One record · two curations

Made for the desk. Made for the hand.

The preparer works at a desk; the signer answers on a phone. Each gets an experience curated for it — never a blanket layout squeezed onto both. Underneath, it is the same databases, the same protocols, the same flow of data.

Two-column workspace: mark up the document, fill once, require fields, sign or send — built for a mouse and a big screen.

Whichever screen you're on, the data flows through the same tamper-evident chain, the same encrypted vault, the same access rules. The curation changes; the truth doesn't.

Why it holds up

Signatures that prove themselves.

Years from now, this is what your signature can say for itself: who signed, when, and where — three questions a typed name answers with silence. YouSignedHere seals all three into the document itself.

Who

The check a paste can't pass

A one-time presence check defeats a still image or a pasted name. It is not facial recognition, no face template is ever made, and the raw check is purged the moment the signature is bound.

When

A moment you can't rewrite

The signing moment is stamped into a hash chain — every later change to the record breaks the chain visibly. Once sealed, the moment can't be quietly rewritten — any change breaks the chain in plain sight.

Where

A place the record can back up

The record starts with the network's own estimate of where the signing happened — honestly labeled. When the signer grants their phone's location, agreement between the two earns the higher tier. The seal names exactly which tier the signature earned.

Tier 1Passkey signature — the phone's own unlock gesture, cryptographically bound to the document
Tier 2+ presence capture — a short, silent, mic-off check, scored on the server and sealed with its verdict
Tier 3+ location consistency — phone and network estimates agree — sealed as a verdict and a rounded distance, never coordinates

The seal names the tier it earned. A declined permission lowers the tier — it never fakes one.

The where, honestly

  • network estimate
  • phone agrees
  • sealed: verdict + distance

The network's own estimate — a wide circle, honestly labeled.

Grant your phone's location and agreement earns the higher tier.

Sealed as a verdict and a rounded distance — never the coordinates.

Nothing to learn

Three moves you already know.

The unlock gesture

Signing starts with the same check your phone runs when you wake it. It happens on your phone — no face template is ever made or sent, and nothing biometric leaves it.

Taps where it matters

Every point that needs your eyes is marked. Each required box takes a tap to complete — "I saw this," not "I scrolled past."

The location stamp

At the end, your phone adds the where to the when — sealed into the record with exactly how it was confirmed, and the tier it earned. New seals also seek an independent RFC-3161 timestamp — a neutral third party attesting the record existed by that moment — and the seal reports the anchor's outcome either way. Sending to someone else instead? Same three moves, on their phone.

You signed. Here.
